摘要: The transport of methanol through Nafion® membrane in diffusion cell is investigated using the open circuit potential method at different initial concentration solutions. A simple mathematical model based on quasi-steady-state for across a developed to simulate experimental data order measure permeability. influence parameters and thickness permeability measurement has been evaluated analyzed. By means Maclaurin expansion technique, this can be used predict deviation determined by steady-state model.
